Abstract
A wireless radio communication apparatus and method in which directional transmission, also known as beamforming, training is performed on transmissions between multiple wireless radio communication devices participating in a local network. A sector level sweep (SLS) process uses transmitter sector sweep (TXSS) training, which includes transmitting a sector sweep (SSW) followed by generating sector sweep (SSW) feedback to other nodes in the local network, with optimum transmit sector information being exchanged between nodes. Embodiments include a power save mode, a delayed SSW feedback mode, and an embedded polling and feedback mode.
